JOHN CHESTER, OF PROVIDENCE, RHODE ISLAND.

STOVE-KNOB.

SPECIFICATION formingpart of Letters Patent No. 253,509, dated February 14, 1882. Application filed December 12, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN CHESTER, ofProvidence, in the State of Rhode Island. have invented an Improvement in Stove-Knob=, of which the following is a specification.

My invention relates particularly to the sheet-metal knobs applied to the doors of stoves and similar uses; and it consists in the improved method of securing the nut at the inner end of the knob, as hereinafter fully set forth.

Thefigure represents a longitudinal section of the knob as attached to the door.

In the drawing, A represents the door ofthe stove, and B the fastening-screw, passing from the inside through a hole in the door. 0 is the nut. D is the sheet-metal body-piece ofthe knob, and E the end cap. F is a sheet-metal cap, which is forced over the end of the bodypiece D and the inelosed nut O, and is made of sufficient thickness of metal to exert a binding force upon the circular edge of the not through the inner material ofthe body-piece D.

In putting the knob together the nut O is first forced tightly against the inner surface of the end of the body-piece D, the sides of the body-piece at; the end thereof being made to closely fit the edge of the nut. The thick cap F is then forced over the end of the body-piece, so that the nut will be securely held and prevented from turning. The edge ofthe end cap is then spun over the outer edge of the bodypiece, thus closing the knob.

By my improvement 21- strong, cheaply-constructed knob can be made, the nut beingfirmly secured at the end of the knob without liability of becoming loose.

I claim as my invention- In a stove-knob, the combination of the nut (J, body-piece D, re-enforcing cap F, and end cap, E, substantially as described.

JOHN CHESTER.
